Each year, U.S. facilities generate around few dozen billion pounds of chemical waste. A major of these waste are categorized as toxic release because they might cause cancer or other chronic human health effects or significant adverse environmental effects. Another major part of these are believed to generate greenhouse gas that accelerates the climate change.
According to Environmental Protection Agency(EPA), over 20,000 facilities report their toxic release and greenhouse gas emission each year. But which industries are contributing the most?
Manufacturing, Utilities, Administrative and Support and Waste Management and Remediation Services, Mining and Wholesale TradeMoreover, when looking at the GHG and Tri ranking, the number of facilities reporting this number decrease further more so in the next sections, I will focus on specific type of industries when looking at average quantities.
Manufacturing rankingWe’ve seen that the Facilities in this dataset are mostly about Manufacturing, Utilities and Mining. I define a new categories to disentangle between these 3 primary industries and the other, for plotting purposes.
Bad player for Greenhouse Gas RleaseLooking at the relationship of Ranking and emission also reveals what type of industries are the main contributor for the GHG gas.
Again we see that the industries with larger emissions of GHG are Manufacturing, Utilities, Mining, resulting in some Facilities having a pretty bad rank. And the top 10 bad players can be seen from the chart.
Bad players for Toxic RleaseTRI emission are Manufacturing, Utilities and MiningGHG emission seems more balanced between these two types of industries, however Manufacturing, Utilities and Mining have the larger contributors (in term of pounds)Sum the gas emission per industry, across all States
Manufacturing, Utilities are the 2 main contributors from 2010 to 2014, with no sign of decreaseAgriculture went from 70k to ~2800 tons in 5 yearsManagement decreasd its emission almost close to 0 !Construction almost doubled its emission between 2013 to 2014Manufacturing, Utilities are (again) the two main contributors from 2010 to 2014, with no sign of decreaseFinance did a great job by decreasing its GHG emission to <1000 poundsAlthough the idea of gas per State is not appropriate (gas are not contained to state limits), we can however get an idea of which States has the lerger initial gas emission, by summing all Facilities values within a State.
